GDS provides a leading range of direct and simple shear testing systems for geotechnical applications. The direct shear test is a key method for determining the shear strength of soils and rocks by shearing a specimen along a predefined plane. GDS equipment ranges from standard shearboxes used in commercial laboratories to advanced systems with precise back pressure control for realistic simulation of field conditions.
For more advanced testing, GDS offers simple shear systems such as the EMDCSS and VDDCSS, supporting static and dynamic testing in one or two directions and enabling research into complex soil behaviour under cyclic and variable loading. The range also includes best-selling systems such as the versatile Shearbase System (GDSSS), the Large Automated Direct Shear System (GDSLADS) for larger samples, and the Back Pressured Shearbox (GDSBPS) for enhanced control, alongside a wider portfolio of additional solutions. These systems are trusted worldwide for their accuracy, flexibility and automation.
